Scientists have recently discovered that the hawksbill sea turtle found in the waters off the Solomon Islands is neon green and red.

Some of the red on the hawksbill could be caused by algae on the shell that was fluorescing, but the neon green is without a doubt from the turtle, scientists told the National Geographic, which first reported the discovery.

Prior to this, scientists have known of corals that use fluoresce, as well as a number of fish, sharks, rays, tiny crustaceans called copepods, and mantis shrimp.

Marine biologist David Gruber, of City University of New York, found the fluorescent sea turtle by chance when he was diving in the Solomon Islands in late July and planning to film the phenomena in sharks and coral reefs.

He only caught a quick glimpse of the turtle, but was able to notice its startling colors before it swam off into the deep ocean. Gruber confirmed his findings by comparing them with captive young hawksbills kept by local residents.

"I've been [studying turtles] for a long time and I don't think anyone's ever seen this," said Alexander Gaos, director of the Eastern Pacific Hawksbill Initiative, who was not involved in discovering the new turtle. "This is really quite amazing."

It's not entirely certain why the turtles have the ability to fluoresce, but it could be a form of camouflage.
